The 2017 NASCAR Cup Series was the 69th season of professional stock car racing in the United States and the 46th season of the modern era Cup series. The season began with the Daytona 500 on February 26, 2017, and ended with the Ford EcoBoost 400 at Homestead-Miami Speedway on November 19, 2017.
The 2017 Cup Series featured several changes, including the introduction of a new stage-based race format that divided races into three segments, each with its own winner and points distribution. The top 10 drivers at the end of the first two stages earned bonus points, and the race winner received five bonus points as well as an automatic berth in the playoffs.
Martin Truex Jr. dominated the 2017 season, winning eight races and earning a total of 19 stage wins. He also won his first Cup Series championship, beating out Kyle Busch, Kevin Harvick, and Brad Keselowski in the final race at Homestead-Miami Speedway.
The 2017 season also saw several retirements, including Dale Earnhardt Jr., who had announced his plans to retire at the end of the season. Earnhardt Jr. finished his final season with 22 top-10 finishes and one pole position.
Overall, the 2017 NASCAR Cup Series was a competitive and exciting season, with the introduction of the new stage-based format adding an extra level of strategy and excitement to the races. Martin Truex Jr.'s dominant performance and first championship win were a highlight of the season, and the retirement of Dale Earnhardt Jr. marked the end of an era for NASCAR fans.
